Mobile efficiency fuels the HVAC industry, and as a building administrator, it’s your job to be able to troubleshoot all possible issues to the best of your ability. In the past, this was easier said than done, but with today’s modern technology, troubleshooting even what looks like the most difficult task is entirely possible. Let’s take a look at some of the best HVAC troubleshooting apps currently available to help you get the job done.

Top 8 HVAC Troubleshooting Apps

1. HVAC Buddy

HVAC Buddy is an all-inclusive, award-winning app that diagnoses problems and helps to find a solution for nearly any repair. It’s capable of determining the proper refrigerant charge for 73 options, such as Puron and Freon. Other features of this user-friendly app include Superheat and Subcool tables; Airflow/Delta-T/TEET Calculation; leaks, contaminants, and overcharge diagnostics, detailed step-by-step instructions, knowledge base access, and more. Further, it updates temperatures in real time, providing instant information that lets you know the efficacy of your troubleshooting.

HVAC Buddy apps is available for both iOS and Android at a cost of $9.99.

2. iManifold

iManifold is an ingenious app that calculates HVAC/R system performance, as well as troubleshoots problems that may be present within the system. It allows you to easily input live system data in order to get down to the root cause of the instability in the unit. You can even customize equipment profile options for whatever type of unit you may be working on.

With over 40 selectable refrigerants and the customization capabilities, iManifold can be specially tailored for a particular unit. The display shows the system’s actual pressures, temperatures, and Superheat and Subcooling, while performing its calculation.

3. HVAC Toolkit

This all-in-one HVAC toolkit offers up an array of incredible apps, all of which will prove useful. While the “Ultimate” configuration offers up a few more apps, even the simplest configuration has more than enough to keep you satisfied. Included are tools like a pressure-temperature chart, steam tables, psychometrics lookups, refrigerant charge calculator for both Superheat and Subcool, and more.

The simplest — but still complete — configuration of this type of HVAC troubleshooting apps is available for both iOS and Android at a cost of $23.99, while the HVAC Toolkit Ultimate is available only on iOS at a cost of $59.99.

4. HVAC PT Chart

If you’d rather work with something simpler, the HVAC PT Chart is user-friendly and self-explanatory but incredibly useful in its own right. The most comprehensive pressure-temperature chart currently available, this one spans over 100 different refrigerants and also includes dew pressure-temperature tables for all azeotropic refrigerants. You simply input the temperature, and then the corresponding pressure will display, or vice versa, depending on your needs.

5. HVAC Check & Charge

HVAC Check & Charge allows for the correct calculation of a charge by using one of three calculators available — Airflow calculator, Subcooling calculator (TXV), and Superheat calculator (non-TXV). Determining the right charge will help you to get the system back up and running in no time. Although it might sound a bit complex, it’s actually pretty easy. Simply choose one of the calculators and plug in the specified system temperatures, as well as the latent sensible environment loads. The app will then show the proper system charge and let you know if the charge amount needs to be modified based on the conditions.

HVAC Check & Charge is available for both iOS and Android at no cost, making it one of the best HVAC troubleshooting apps for professionals who do not afford to spend a lot of money on software.

6. Refrigerant Slider

Refrigerant Slider provides an intuitive conversion scale that assists you in finding the pressure-to-temperature point. A versatile app, it includes 69 options for both traditional and natural refrigerants, and provides specific information for each of these refrigerants, like the Ozone Depleting Potential (ODP) and Global Warming Potential (GWP). The dew point and bubble point is also shown for each refrigerant. Based on NIST Refrigerant Properties and using the Antoine equations for conversions, this app is a must-have.

Refrigerant Slider is available for both iOS and Android at no cost.

7. ABM-100 (Airflow Balancing Meter)

The Airflow Balancing Meter app, officially titled ABM-100, is incredibly useful and intuitive, thanks to its ability to automatically measure airflow velocity and calculate airflow volume. Pairing your smartphone with the widely available ABM-100 airflow meter headphone jack attachment allows you to get an accurate idea in terms of how much air is flowing through the ducts. It measures velocity in linear feet per minute and meters per second, as well as calculates airflow volume in cubic feet per minute and cubic meters per hour.

Airflow Balancing Meter is also one of the great HVAC troubleshooting apps available for both iOS and Android at no cost.

8. HVAC Professional Formulator

HVAC Professional Formulator includes 200 formulas and 18 charts pertaining to various areas in the HVAC industry. It also provides users with the complete International Mechanical Code. This all-in-one app provides a simple way for you to quickly find what you’re looking for — you can easily search, mark your favorite formulas, and access recently used formulas. Best of all, app updates are constantly being performed, adding in new formulas and other useful features to ensure that it’s always relevant to the current industry.

HVAC Professional Formulator is available only on iOS at a cost of $7.99.

It’s obvious that there is an overabundance of HVAC troubleshooting apps on the market today; that’s why it’s especially important to whittle down your options to the best ones available. But only upon trying any number of these apps will you be able to determine how useful they will be for you personally. Some might suit you, others might not, but that all depends on the situation and what type of issue you’re attempting to troubleshoot — so give each app a fair shake and see which ones work best for you.
